Jadex BDI Agent = System - Overview (About.Overview)

Mission Statement

Intelligent agents are a modelling paradigm, based on the notion of = agents=20 with mental states. The Jadex reasoning engine follows the Belief Desire = Intention (BDI) model and facilitates e= asy=20 intelligent agent construction with sound software = engineering=20 foundations. It allows for programming intelligent software agents in = X= ML and=20 Java and can be deployed on different kinds of middleware = such as=20 JADE.

To enable the creation of intelligent agents several different = constituent=20 parts have to be assembled. It is necessary to provide an agent = architecture=20 that at least takes into account agent-internal, agent society and = artificial=20 intelligence (AI) concepts. It is a property of agent research that = interesting=20 research results in various isolated areas exist, but that these results = are not=20 integrated into superordinated architectures. Therefore until now no = standards=20 can address the construction of intelligent agents in all facets.

Summary

The Jadex research project is conducted by the Distributed Systems = and=20 Information Systems Group at the University of Hamburg. = The=20 developed software framework is available under GNUs LGPL license, and = is=20 continuously evolving. The project's file releases are kindly hosted by = the=20 SourceForge.net portal.=20 The projects web presence is based on a wiki and thus allows Jadex users = to=20 contribute in various ways. The reasoning engine has been put into = practice in=20 the context of several = research,=20 teaching, and industrial application scenarios some of which = are=20 described here in the web.
